Its burrow, which can be 2.5 m (8 ft 2 in) long and 1.5 m (4 ft 11 in) deep, consists of a nest chamber, several storage chambers and chambers for the waste. Siberian chipmunks usually live solitary lives, but during the winter they create a burrow, which they often share with another chipmunk. This method illustrates one way in which this species communicates with one another. The Siberian chipmunk marks its territory with urine and oral glands inside of its cheeks. The territory ranges from 700 to 4000 m 2 and is larger for females than males and is also larger in autumn than spring. The Siberian chipmunk lives in loose colonies, where every individual has its own territory. Also they have trouble overcoming man-made and naturally occurring obstacles, like roads or swamps. However, this species has a low ability of dispersal, and since they are mainly introduced into woody forests or urban areas with greenery, they have less potential to be naturally dispersed to other regions. Tamias sibiricus is able to survive in various environmental conditions, anywhere from 29°N to 69°N and −65 ☌ to 30 ☌. In Europe, the introduced populations usually live in deciduous forests, mixed deciduous and coniferous forests, or urban areas with greenery. They are usually found in coniferous forests, stony areas within forests and mountains, habitats filled with shrub, along waterways or roads, or other small patches of agricultural land. The Siberian chipmunk can survive in a variety of habitats and conditions. Habitat Eutamias sibiricus near Lake Kuyguk This mandates that the species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. In Europe, the Siberian chipmunk is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). In 2009, 22 introduced populations in Europe, and 11 in France, were identified in forests and urban parks since the 1970s (not all may still be extant). While thousands of animals were introduced to new environments, they are not very invasive and are naturally slow spreading, 200 to 250 metres (660 to 820 ft) per year, which prevented them from rapidly moving to areas far beyond where they escaped. When the zoo was shut down and all animals were moved away, many chipmunks got forgotten due to their underground residence. The Dutch chipmunks for example are escapees from a former zoo in Tilburg. Other Siberian chipmunks escaped from captivity and inhabited the forested areas of Europe. This is mostly caused by owners releasing these animals because they no longer wanted them as pets, or the owners purposefully freed the chipmunks to live naturally in the wild. In the 1970s there were sightings in parks in Europe, and a number of small populations have become resident in suburban forests and urban parks in Belgium, France, Switzerland, Germany, Italy, the Netherlands, Austria and Great Britain. Between 19, South Korea exported more than 200,000 individuals to Europe. ĭuring the 1960s, South Korea began to export these animals to Europe as pets. It has been introduced at one confirmed locality, Karuizawa, on Honshu. This species is native to Russia in northern European, Siberia to Sakhalin and Kunashir, extreme eastern Kazakhstan, northern Mongolia, northern and central China, Korea, and in Japan in Hokkaido, Iturup, Rishiri, Rebun, Teuri, and Yagishiri. However, in captivity it lives up to ten years. Its small size may contribute to its relatively short life from two to five years in the wild. The Siberian chipmunk does not exhibit sexual dimorphism, and size and body proportions are the only way to distinguish younger chipmunks from older ones. Even though the Siberian chipmunk normally grows to 50–150 g (1.8–5.3 oz). It exhibits slight variations in coloration in different geographic regions. The weight of adults depends on the time of year and food availability. It is 18–25 cm (7.1–9.8 in) long, a third of which is the tail. Typically the Siberian chipmunk has four white stripes and five dark stripes along the back. It was imported from South Korea and introduced in Europe as a pet in the 1960s. The Siberian chipmunk ( Eutamias sibiricus), also called common chipmunk, is native to northern Asia from central Russia to China, Korea, and Hokkaidō in northern Japan.
